Product Description

1.  ZN63 VS1-24 type 3 phase indoor 24kv 630A vacuum circuit breaker


ZN63-24 indoor H.V. vacuum circuit breaker is an indoor switchgear with three-phase, rated voltage of 24kV, control and protection for industrial and mining enterprises, power plants and substations, electrical facilities, and for frequent operation place adopting VET operating mechanism and circuit breaker integrated design can be used as a fixed installation unit can also be equipped with special advance mechanism, the composition of handcart unit used some of the main circuit can use the whole solid seal post with high reliability, maintenance-free, in order to achieve smaller circuit breakers, can be equipped with KYN28A 24 and other handcart switch cabinet. In the home it can also be used with fixed switchgear.
2. Main features:
⚫Mechanical and electrical durability During rated current, breaking times can reach to 10000, 20000 During rated
short-circuit current, breaking times can reach to 20, 30 and 50 times.
⚫With complete product portfolio Rated current from 630A to 4000A Rated short-circuit current form 20kA to 50kA
⚫ It has the features of series, strong versatility, convenient use and easy maintenance. All products have passed
500 running-in tests according to reliability principle in the factory before delivery, so as to ensure the reliability.
⚫ We will provide you with qualified and high-efficient after-sales service.
⚫ The circuit breaker has complete functions. It is used to switch on/off various loads as specified by DL standards, such as method 1-5, capacitor, out-of-phase conditions.
⚫ Easy maintenance Normally, it just needs to clean the operating mechanism and add lubricants.
⚫Vertical insulating tube Protect it from various environmental impacts.
